Kalocyrma oxygonia is a moth in the family Lecithoceridae. It was described by Chun-Sheng Wu and Kyu-Tek Park in 1999. It is found in Sri Lanka.
The wingspan is about 9mm, and it has orange antennae. It is worth noting that the base and apex are brown, and the full length is not a solid colour. The labial palpi are dark brown, and its head and thorax are a yellowish white.
The species name is derived from Greek oxys (meaning sharp).
